Tommy’s comedy partner Bobby Ball, 69, is already a regular character on the BBC1 show playing Lee’s dad.

“Whenever we need a guest character I always think of the comics I grew up with,” Lee said.

“I’d like to get Tommy, Bobby Ball’s double act partner, in the show at some point. It’d be a nice little cameo appearance. So that’s the next plan.”

The sixth series of the comedy – which has been sold to 120 countries – will air this year.

Lee, 44, added: “How long can it run for? I don’t know. The nature of television is that it’s not always my decision. Usually they come and offer me a new series and I go ‘Oh go on, I’ll do another one’.”
